That makes perfect sense. What are the advantages of the 2793 over the 1771 and 1773 as long as you get a good working 2793?

What a wealth of information! I guess I asked in the right place. What is the socket right in the middle that is un-populated for? Is that just where the board is soldered down to the main board? So I assume from what you are saying is that a 2793 is hiding underneath that daughter board? I already put it back in the casing but I can remove it again to take pictures of the back side if you would like them.

Hello Its been many years that my TI has been in storage. My family is doing some very late Spring Cleaning and I just came across my TI which collected a lot of dust. After going through all of my parts I decided to tear down my expansion box and clean it up as good as possible. I also thought that I might have to re-cap some of my boards as they have sat a long time. I opened my Corcomp disk controller casing and to my surprise it is unlike any that I have seen before. Their is some type of add on board or modification where the Western Digital chip goes. Any ideas on what this mod is or does? I would also like to get some advice as if I should re-cap my boards or leave them until I run into a problem. They all seem to work but I have OCD and like to normally fix/repair things just due to age.
